Golovko M. The influence of elemental and petrographic compositions of coals and blends on coke and coking by-products.

The thesis is devoted to theoretical and experimental justification of interrelation of element and petrographic compositions of coal (blends) with output of coke and coking by-products. The quality indexes of elemental and petrographic compositions and the major products of coking coal concentrates in Ukraine, Russia and the United States the most widely used in the resource-based of coking of Ukraine are experimentally determined. The method for determination of the coke and coking by-products and draft DSTU "Hard coal. Method for determination of chemical coking products yield" is improved; inertinite and semivitrinite components, as well as liptinite part are given subjects to differences in the composition and structure of the organic mass of coal, expressed complex index of the degree of molecular matter of coal association.
